What weight is 11 mil paper?

11 mil paper refers to the thickness of the paper rather than its weight. A mil is a unit of measurement equal to one-thousandth of an inch, so 11 mil corresponds to 0.011 inches thick. The weight of this thickness can vary depending on the type of paper and its density, but it is often used for materials like cardstock or photographic paper. To determine the specific weight, you would need to know the paper's basis weight, usually measured in pounds per 500 sheets of a specific size.
